一种高炉粗煤气管道内衬喷涂修补料及其使用方法
摘要：
本发明涉及一种高炉粗煤气管道内衬喷涂修补料及其使用方法，修补料包括以下原料组份：按重量百分数，合成莫来石颗粒0-65%、低铁特级焦宝石颗粒0-65%、合成莫来石粉10-20%、结合粘土粉2-5%、SiO2微粉2-5%、高铝水泥13-18%；以上述原料组份混合物总重量为基准，还包括：促凝剂0.05-0.1%、FDN高效减水剂0.1-0.5%、糊精1-1.5%、有机纤维0.05-0.15%。本发明的喷涂修补料具有抗CO侵蚀、耐冲刷、早强可快速修补、使用寿命长的特点，具有良好的应用前景。
摘要（英）：

The invention relates to a blast furnace raw gas pipeline lining spraying patching material and a use method thereof. The patching material comprises the following raw material components by weight: 0-65% of synthetic mullite particles, 0-65% of low iron special grade flint clay particles, 10-20% of synthetic mullite powder, 2-5% of binding clay powder, 2-5% of SiO2 micropowder, and 13-18% of high aluminum cement. On the basis of the total weight of a mixture of the raw material components, the patching material also includes: 0.05-0.1% of a coagulation accelerator, 0.1-0.5% of an FDN superplasticizer, 1-1.5% of dextrin, and 0.05-0.15% of organic fiber. The spraying patching material provided in the invention has the characteristics of CO corrosion resistance, scouring resistance, early strength, fast patching, as well as long service life, thus having good application prospects.
